Beit known that we, Annor Aveos'r'ps Lonqand AUGUST \Vassrulnn, citizensof the United States, re-

siding, respectively, at Horseshoe, St. Lawrence county, State of NewYork, and at Halletts Point,

Astoria Queens county, State of New York, have invented certain new anduseful Improvements in'H'ys ,drocarbon-Motors, of which the following isa specification.

Our improvements relate to the class of motors in which'liquidhydro-carbon is vaporizecl'and mixed with air to form thecharge 'which-is exploded in the combustion chamber, and the present'inventionrelates essentially to the means employed for effecting thepreliminary heatingand starting of the motor,

said operation.

To this end the invention consists essentially in the provision of meanswhereby an auxiliary. supply of liquid hydro-carbon be made toimpinge-upon a vaporizing plate, the temperature of which may be quicklyraised to the vaporizing point by an electric heater, which may beswitched on or off instantaneously as equircd. The invention alsoincludes means. for admiing air to the vaporized hydro-carbon andintroduci g the mingled air and vaporized hydrocarbon into the mainmixing chamber immediately adjacent to the induction valve between saidmain mixing chamber and the combustion chamber, so that thesepreliminary charges used in starting the motor, will be immediatelyintroduced into the combustion chamber with little or no loss of heat byradiation or by absorption by the walls of the main mixing chamber.

The accompanying drawing represents diagrammatically and in sectionalelevation, the parts of a hydro-mrbon motor essential to anundcrsurnding and practical operation of our invention.

P is the rccipnxrating piston within the cylinder C, the upper part c,of which constitutes in this case the combustion chambcr, in which thesuccessive chargm are exploded by a sparking device S, of any dcsircd orwell known construction.

M, is the main mixing chamber in which, during the normal running of themotor, liquid hydro-nirbon is forced through an injector I, in the usualmauncr, the liquid hydro-carbon thus injm-tcd being made to impingeagainst a perforated scrccn m', as heretofore, said screen 122, beinginterposed between the injccwr I and the automatic induction valve V,which in turn is intcrposml between the main mixing chamber M. and thecombustion chamber c, in 'the cylinder C. Air is admitted to the mainchamber through a damper l), as hercwiore to bc mixcd with the vaporizedhydrocarbon bcforc its intrmluction into the combustion Specification ofLetters Patent.

chamber. After the preliminary heating and starting of the motor, thefeeding and operation of the motor isthe sameasusual. i v

The main noveltyin the present application consists in the use of a;relatively small auxiliary chamher A, and accessories hereiriaiterdescribed, whereby preliminary charges of vaporized hydro-carbon mixedwith air may :be introduced into thelpwer'part otthe Y main mixingchamber immediatelyabove'nnd-adjoiri- 1' ing the induction valve V,which-is Ol s d as here tofore by suction caused by the-piston. For thisreason the auxiliary vaporizing A, is connected ir'ectly by a conduit awith the lower portion of the main mixing chamber M, in proximity toinduction valve V, substantially as illustrat'd 'inthe accomranying d gWithin a anxiliary mixing the.

the plate 1:. when the main induction valve V, is open.

By the use of thc supplementary moans above described (or (fft'Ctlllgthc preliminary heating and starting of the motor we are enabled tomaterially shorten the' said o xeration. nincc thc va mrizing plate b,maybe miscd almost inslanlanmusly by thcieloctrical heating device to atcnqwmturc sullicicnt to died, the vaporization oi the liquidhydro-(arbon.
